Lincoln Center will not stage The Tristan Project at New York's Seventh Regiment Park Avenue Armory next spring as originally planned, the venue announced today.

Instead, the multimedia version of Wagner's Tristan und Isolde, a collaboration between video artist Bill Viola, director Peter Sellars, conductor Esa-Pekka Salonen and the Los Angeles Philharmonic, will be seen at Avery Fisher Hall. Because of the change of venue, the dates for some performances have been changed and others have been canceled altogether.

The Tristan Project was to be presented in its entirety on April 27 and May 5, 2007; it will now be seen on May 2 and 5. Three additional performances in which each of the opera's three acts was to be paired with a work by Debussy, originally scheduled for April 30, May 1, and May 2, have been canceled.

In a statement, Lincoln Center said that building a custom performance space in the Armory in the time remaining before the performances proved to be "prohibitively expensive."

"Though the size of the Armory's raw space made it desirable for the presentation's large video screens," the statement read, "it became apparent that existing air conditioning, restroom, and other patron amenities would be inadequate for the expected number of ticket holders."

Plans to convert the Armory into a performance space will still go forward, Rebecca Robertson, the president and chief executive of the Seventh Regiment Armory Conservancy, told The New York Times. But those plans may take several years to carry out.

For performances of The Tristan Project, Lincoln Center will reconfigure Avery Fisher Hall, adding a thrust stage as it did for last year's Mostly Mozart Festival (and as it will for this year's festival). That configuration means that the physical layout of the production, which premiered on the thrust stage at Los Angeles's Walt Disney Concert Hall, will not have to be altered.

The performances will star Christine Brewer as Isolde, Alan Woodrow as Tristan, Anne Sofie von Otter as Brang‹ne and John Relyea as K‹nig Marke.

Lincoln Center will contact ticket holders with information on refunds and exchanges. Ticket holders may also email customerservice@lincolncenter.org or call 212-875-5456.
